Case for Seidio Innocell 3500 Extended Life Battery

I really want to get this battery, Seidio Innocell 3500 Extended Life Battery, for my Treo Pro, but it looks like there are not any cases available for the extended life battery. Or maybe I am not looking hard enough?

Does anybody know or can recommend a case that will fit this battery? I would prefer a skin, but anything that is out there would be fine.
